OPTION INFORMATION
Encode
Export
Data If this option is enabled, all tracking files will be encrypted during
export in order to make sure that exported data cannot be read or
manipulated by any unauthorized person. A password is required to
enable or disable this option. The exported text file can be decrypted
by a separate decoder tool. Usually this is done at the tracking center
which receives the exported file. A description how to decrypt the
tracking file and the password to enable or disable this option is only
provided to an authorized person on request.
Test
Settings The Test Settings area allows the user to enable (checked) or
disable (unchecked) the following features that occur during a
measurement (Figure 60). The different options are described below.
Figure 60
Display
EEG
(Screening) Sets the EEG view as the default when enabled; otherwise the quality
indicator bar is displayed above the measurement graphic during data
collection.
Beep after
test E
nables an audible “beep” that occurs when a measurement is
complete. The quality and audibility of the beep may be affected by
the specific PC that is used.
Automati-
cally close
test
distortion
message Enabling of this control causes a pop-up message regarding test
distortion to disappear automatically. When disabled, the user must
manually close this message that occurs immediately after an
impedance test when cyclical noise is detected in the EEG signal.
Allow
reduced
test time When disabled, a REFER outcome will be recorded after 180 seconds
of data collection when the algorithm detects no response.
With this feature enabled, a blue box is displayed in the time graph in
the measurement screen. If the test progress line remains below the
horizontal line of the blue box, then the test will end at 120 seconds
with a
REFER . If the test progress exceeds the upper limit, then the
test will continue for the full 180 seconds.
When enabled, tests that do not reach 60 % of the statistical value
required for a
PASS within 120 seconds will stop automatically with a
REFER result. Statistical analysis of a large sample of screening data
has shown that very few tests (0.09 %) will Pass with a full
180 seconds test duration under these conditions.
